Sunday’s Formula 1-grandprix at Silverstone in England was a dramatic conclusion.

The two Mercedes cars, as well as Carlos Sainz’ McLaren were all affected by the punctures towards the end of the race, which meant that Lewis Hamilton had to drive over the finish line as the winner with only three functional wheels.

The many punctures in a short time was Formula 1’s dækleverandør, Pirelli, to initiate an investigation, which is now completed.

the Reason for the flat wheels was that they had been in use for a long time and was congested, sounds.

– the Main reason can be boiled down to a number of individual circumstances that led to an extremely far use of the second set of wheels, writes Pirelli on its website.

– The second safety car period got almost all of the teams to run in the pit and thus end with a very long period of time after the last pit-stop, about 40 laps, which is more than three-quarters of the total løbslængde on one of the most demanding tracks in the calendar.

in Addition, the increased speed this season to make the final laps of Sunday’s race extra hard for the tires, says the tire manufacturer.

While Lewis Hamilton held on to his lead Sunday and won, so fell his team-mate, Valtteri Bottas, who was number two, back on 11.-square.
